I believe it's an sc560 code out- press roller temp diminishes, and machine codes out. Replaced fuser, and power supply. After replacement of power supply, press roller temp did not drop as rapid, but still will not hold at defualt 150 deg. Any help appreciated, thanks.

please verify code. I see sc561 for press roller. Could be thermistor or thermopile or just connector.

That's correct c561, sorry - found that it was the BICU board, replaced with the original fuser and had the same issues, to find that the board took out the T stat on the press roller. double wammy.

ouch!!!
nice piece of troubleshooting though. I hate it when it is a pcb. It always sounds like a generic hotline suggestion.....
